Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528210, here are decompositions:

13 + 528197 = 528210
19 + 528191 = 528210
43 + 528167 = 528210
47 + 528163 = 528210
73 + 528137 = 528210
79 + 528131 = 528210
83 + 528127 = 528210
103 + 528107 = 528210

Showing the first eight; more decompositions exist.
